The invention relates to driving lights for i motor vehicles and has'for its'object the pronism to move the lamp on a vertical axis, so

' that the rays of light therefrom will be thrown in the direction in which the automobrackets having bile may be proceeding in rounding curves as well as straight away driving.

A further object of the invention is the provision of a driving light thatis adapted to be used as an accessory for'automobiles generally, being adaptable to different types of automobiles. 4 A further object of the invention is the provision of an accessory of the character stated comprising brackets adapted to be mounted on the frame of an automobile, one of said a threaded socket to receive a screw member to hold a standard, in an adjusted position relatively to the frame, said standard having a bearing for the lamp shaft, the other bracket having a bearing for a horizontal shaft that is extensible through an opening in the adjacent wheel fender, the lamp shaft :and the horizontal shaft having arms connected by adjustable links, and the horizontal shaft also having an arm secured thereto that is connectible with the rocker shaft of the vehicle, said construction providing for moving the lamp shaft so that the rays of light from the lamp will at all times llze thrown directly in front of the automoile.

The invention will be described in detail hereinafterand' will be found illustrated'in V the accompanying drawings in which Figure 1 is a side view of afragment of an automobile showing the dirigible driving light applied thereto, 3

'Figure2 is a top plan view of thedriving light, 7 r

Figure 3 is a sectional detail on a plane indicated by the line 3--3 of Figure 1, and

Figure 4 is asectional detail on a plane indicated by the line 44 of Figure 1.

In the drawings similar reference characside sill B, the bracket 1 as may be desired by the operator.

ters are used to designate corresponding parts 7 throughout the severalviews.

The improved, driving pliedto .amotor vehicle suggested at A having a side sill B and a wheel fender G. The accessory comprises two brackets designated 1 and 2 that are-adapted to be secured to the being provided with a threaded'socket 3, while the bracket 2 is provided with a bearing 4 in which is j ournaled in a horizontal shaft 5'. Supportedon the bracket 1 is'a standard 6, having longitue dinal slots 7 through which is secured a set bolt 8 engaging in the threaded socket 3, this structure providingfor adjusting the standard up and down or' at an angle to the vertical Standard 6 is provided with a bearing 9' in which is journaled to ,thelamp post 11 by means of a pin 12, 13 designating a lamp that is secured to the lamp postll in the ordinary manner as suggested at 14.7 15 ndicates a cushion spring encloslng shaft 10 'and'bearing againstthe lower end of the bearing 9 and the disk 16 connectedlto the which is secured bifurcated clips 24 by means of threaded sockets 25 engaging said threaded ends, the arms of said clips 24 having their ends enlarged and provided with recesses or light is shown ap- I openings 26 to receive the ball end 19 or 21, as 1 the case may be. This structure of joint between the clips 24 and the balls 19 or 21 provides a limited universal movement between the clips and the balls to permit the rod or link 22 to adjust itself automatically in operation. The bifurcated clips 24 are provided with clamping screws 27 to hold the arms of the clips in engagement with the balls 19 or 21. v28 designates jamb nuts mounted on the threaded ends of the rod 22 back of the threaded sockets 25 to hold the rod 22 in adjusted positions in the sockets. 29 designates an arm secured to the shaft adjacent to its outer extremity, said shaft being passed through an opening 30 in the apron of the wheel fender C, and said arm is provided with an angular extension 31 having a ball end 32 that is engageable by a bifurcated clip 33 that is similar in construction to the clip 24, having an opening or recess 34 to receive the ball end 32 and a clamp screw 35 to hold the arms of the clip 33 in engagement with the ball. Clip 33 has a threaded socket 36 to receive the threaded end 37 of a rod 38, said rod having its other end provided with an angular extension 39 that engages one member 40 ofa clamp 41 that is adapted to be secured to the rocker arm D of the motor vehicle.

In operation it will be apparent that as the rocker arm B is moved backward or forward in steering the motor vehicle movement of the lamp will be imparted through the shaft 5 by means of the rod 38 connectedto the arm 29, and through the rod 22 connected with the arm 20 and arm 17 secured to the lamp shaft 10 to the lamp post 11 so that the lamp will be turned on a vertical axis and the rays of the light therefrom will be thrown in front of the vehicle at all times whether driving straight ahead or making right or left turns to illuminate the road around the curves.

What is claimed is In a driving light, a bracket adapted for attachment to the frame of a vehicle with one end projecting laterally beyond such frame,

a standard abutting the outer end of the bracket and adjustable about a horizontal axis and fastened to said bracket,rsaid standard at its upper end having a thickened portion forming a bearing integral therewith projecting laterally therefrom and overhanging said bracket in spaced relation thereto, a lamp'shaft j ournaled in said bearing and extending into the space between said bracket and said bearing, and means for dirigible operation connected to the shaft in said space.

In testimony whereof I affix my signature.

WILLIAM R. JOHNSTON.
